My GF let me borrow her Canon XSi SLR camera and I was having fun with the settings. I tried various modes, custom white balancing, and exposures. Here are some pics of my JBJ Nano Cube 12 Gallon DX I set up a while back for freshwater. I hope to one day get a larger tank but this 12 gallon will suffice for now. It really has that big tank feel in a small package though, so I'm happy.

Thanks for checking out my pics!
